Bronica lenses

Jump to: navigation, search

Bronica was originally unable to manufacture it's own optics and hired Nikon. The early cameras of Bronica were focal plane SLR cameras such as the Bronica S2, C2, EC, etc. offers a unique optical design.

Unlike more complicated leaf shutter lens designs, these Bronica lenses do not require built-in shutters or focusing. The lens mount can also attach in three different ways with a large bayonet, small bayonet and a 57mm screw mount with a 1mm pitch. This made it easier for manufacturers to easily produce many different types of lens heads that share the same focusing module. This also made it easy for many companies to manufacture automatic or preset diaphragm modules with built-in focusing to attach to an existing lens head design not originally made for the Bronica. This is also great for making, adapting and hacking your own lens.

Nikon decided not to manufacture lenses for Bronica, so the company decided to produce their own optics under the brand name Zenzanon. This situation led Bronica to have a very low supply of the standard 75mm lens when they were to announce the newer Bronica EC series of cameras. Alternatives were needed and a 80mm f2.8 MC Zenzanon by Carl Zeiss Jena DDR was produced. A variety of different Zenzanon branded focal length lenses were made as the supply of Nikkor's decreased.

Cameras like the ETR, SQ and GS use leaf shutter lenses.
